SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

Speclication of Letters Patent.

Patented June 80, 1914.

Application filed May 28, 1910. Serial No, 563,996.

livery Apparatus for Printing-h/Iachines, ofv

which the following is a specification.

The object of this invention is to provide certain improvements' in the construction, form and arrangement of the several parts of asheet delivery apparatus -for printingbr r machines whereby diilercnt lengths of sheets maybe positively forwarded to the sheet delivery device 4by a positive sheet forwarding device adjustable toward and away from the delivery device, and released as their advance'edges are engaged by the delivery device.

This invention further contemplates an endless sheet delivery, carrier driven at a certain speed, a sheet feeding endless tape carrier riven continuously at a higher speed and positive sheet forwarding rolls driven lov and at the speed of the tape carrier, said forwarding rolls being adjustable along the tape carrier for causing it toV cngage and release different lengths 'of sheets at redetermined times.

n the accompanying` drawings, the invention is shown in connection with a two revolution rotary cylinder printinfr machine but it is .to be understood that .it may be applied to printing machines ofvarious VIn the portion of. the 'printing press here-- in shown, the form cylinder denoted by l and' itsimpression `cylinder by 2. The form cylinder gear 3 is driven :from av gear 4 on thedrive shaft 5, which shaft is driven from asuitable motor 6. The form cylinder gear 8-n1eshes with the impression cylinder gear 9'. A sheet delivery' device is provided for depositing the'sheets as they are fed from the impression cylinder 2, which device may', for instance, he :in endless delivery carrier 10, such as that shown, described and claimed in my nii-pending appli cation filed June 8, 1905), Serial No. 500878,'

wh ich endless delivery carrier is driven :from thedrive shaft 5 through the spur gears i, 1l, bevelzgears 12, 13, and shalt 1i. 'lhis endless delivery carrier lO-uiay he provided with one or more sets of sheet grippers l5 operated at suitable intervals to receive and deposit the sheets. I

This present invention is directed to im proveniente in the means for couvifeying the sheets from the impression cylinder to the sheet delivery carrier and constructed, arranged and operated as follows :mii continuously `driven endless tape carrier is interposed between the sheet delivery carrier 10 and` impression cylinder 2; This tape carrier comprises the tapes 16 which pass around pulleys 1T on the rotary shaft 18 at their inner' ends and around pulleys 'itl on a rotary shaft El() at their 'outer ends.

y The sheets as they leave the impression cylinder pass between thc sheet guides 2l and the Stripper fingers 22 onto the tapes 1 (3. These sheet uides 21 extend outwardly to the point w 1ere th'e sheets are delivered from the endless tape Acarrier to the endless delivery carrier l0 and they arc supported upon cross rods 23, 23. At the outer end of the endless tape carrier, sheet guide lingers 24 are provided below the, outer ends oif the sheet guides 2l, between which guido lingers 24 and guides 21 the sheets are fed from the endless tape carrierto the endless deliveryv carrier. The endless tape carrier is driven continuously at the spoed of the impression cylinder as followsm;y drivingr llclt 35 passes at its inner end iround a pulley 2G on a cross shaft' and at its. outer end aroiind a pulley en the cross shalt 120'. This shaft 27 is driven through a geared' connection 29, 30, from the impression cylluder gear l). Coacting sheet i'orwnrifling rollers 31, 32, are located in proximity to the impression cylinder, the roller 8l living mounted on the shall 2 4 and the roller 55:2 on a cross shaft 33.

A positive sheet forwarding device is pro vided Llor engaging the shoots on the endless tape carrier and positively forward the sheets into position lo he engaged hy the` grippers 15 on the endless, dcllvcry carrier lia) is adjustable along the endless tape carrier machine.

extends substantially parallel with the tapes toward and away from the endless delivery carrier whereby diiierent lengths of sheets may be released by the positive sheeti'orwarding device as the advance edges of the sheets are engaged by the grippers on the endless delivery carrier. rlhis positive sheet forwarding device is constructed, arranged and adjusted as follows z-The forwarding rolls are denoted by 34, 35, and are'mounted on the rotary shafts 36, 37, mounted in side plates 38 having pin and slot con-nec tions39, 40, with the side frames lil of the Each of these elongated slots e0 16 of the endless tape carrier and each side. plate 38 vis provided with two bolts 3?) and their nuts for clamping the side plates at any desired position along the tape carrier toward and away from the endless delivery carrier. These sheet forwarding rolls are driven at the same surface speed as the endless tape carrier and the impres ion cylinderand may be driven by the endless tape carrier as ollowsz-The shai't 27 is provided with a pulley lll* around which a driving belt l passes. This driving belt 42 passes around a pulley43 mounted on a shaft at a dit tance outwardly beyond the sheet forwarding rolls. r[his belt 42 also passes around a pulley 45 on the forwarding roll sha ft 37 and another pulley 46 on a shaft il? mounted in the side plates 38 adjacent to the shaft 37. This arrangement permits the forwarding rolls to be adjusted toward and away from the endless delivery carrier 10 without dis' turbing the driving connection. with the endless tape carrier. l

The sheet guide fingers 24, hereinbeiore referred to, are secured at theproper intervals apartto a cross rod 4:8 mounted in the side plates 38 of the positive sheet forwarding device so that, as the she-et forwarding device isadjusted toward and away from the endless delivery carrier, the guideiin gers 24 are adjusted with it. v

ln operation, the sheet forwarding rolls Y 34, 35, are first adjusted at the required distance inwardly from the delivery carrier 10 to permit the rolls to be released'trorn their engagement with the rear edge of a sheet as the advance edge of the sheet is engaged by the grippers 15 `on the endless delivery carrier. As the sheet of predetermined length is delivered from the impression cylinder between the 'guides 2l and stripper fingers 22, it will be engaged by the feeding rollers 31, 32, and fed along the endless tape carrier until the advance edge of the sheet .is engaged by the forwarding rolls Seh 35. rllhese forwarding rolls will then positively feed the sheet forward until the advance edge of the sheet is engaged. by the grippers l5 0n the endless delivery carrier. it the justalole tow i t, .i t incanta saine time, the rear edge or' the sheet 'will pass 'tronibetween the forwarding rolls thus permitting the endless delivery carrier which travels at a slower speed than 'the tape carrier and forwarding rolls, to bring the sheets out into position to deposit them in the usual manner.

'While i have shown the sheet forwarding rolls as adjustable towardand away 'from the sheet. delivery carrier, it is evident that the carrier itself may and away from the sheet 'forwarding rolls and accomplish the same result. lit is also evident that any form oi: sheet delivery carrier may be used in connection with the sheet ltorwardivog device herein described and it is evident that various changes may be made in the construction, form and arrangement 'ot the several parts without departing from the' spirit, and scope of this invention; hence y l do not wish to limit the invention to the eXactconstruction herein shown, but
